and reliable inside reecting nails, tacks and other sharp objects andpreventing the same from reaching and tube.

With the above and puncturing the inner other objects in View,

the invention consists in the novel construction, combination andarrangement of parts, as herein described, illustrated and claimed. Inthe accompanying drawings z-Figure 1 is a cross section through a tireshowing the protector of this invention in its proper relation to theouter case and the inner tube. ig. 2 is a fragmentary longitudinalsection illustrating the tapered overlapping extremities of theprotector. Fig. 3 is a fra entary plan view'of the outer face of theprotectorshowing one end thereof. Fig. 4 is a fragmentary plan View ofthe inner face thereof.

Referring to the drawings 1 designates the outer caseof a pneumatic tireand 2 the inner tube thereof, both of said prts being of the usualconstruction, Bei ween the outer case and inner tube the protector ofhis invention is interposed. 1

he protector, which is generally designated at A, comprises an innersheet a of chrome leather, an outer sheet 6 also of chrome leather andan interposed core 0.

e inner sheet a has its smooth face 3 disposed-on the inside of theprotector so as to lie in contact with the inner tube 2 usuallysprinkled with soapstone or the like so between the inner tube and theprotector. The outer face 4 of the inner sheet L is rough, is cementedas indicated at 5 to the rough inner face 6 of the core a so as topreobject in view being to and thickness entire longitudinal extent.

which have thus vent any relative movement between the inner sheet andthe core.

he outer sheet 6 has its inner smooth face arranged in contact with theouter face 8 of the core, which outer face of the core is formed ofchrome leather thereby providing two smooth faces which normally rest incontact with each other. The rough side 9 o the outer sheet or creepingmovement between the protector the outer case. The core a is in turnprovided with a subcore d of fiber which ma terial assists in deflectingsharp objects and in the smooth arched outer which serves to deflectsharp objects after they have passed through the tread portion of theouter case and the outer sheet 6 of the protector. sheets, for examplethe sheet a, is made of greater width than the outer sheet Z) as shownin Fig. 3 and sa d narrower sheet is secured along its marginal edges tothe extion 'between the inner tube and outer case, there will be littleor no variation in the of the protector In cross section be primarily tonew outer cases but son that said outer cases were n )t able towithstand the required pressure to support the vehicle and its load,()ld outer cases been unfit for further use One of thedescribed may gasthroughout its 10 sheet of chrome leather having its smooth facedisposed for contact with the inner tube, an outside sheet of the samematerial having its smooth face disposed in the same direction, saidsheets being of difierent 15 widths and the marginally fastened to thesheet of greater pneumatic tires to be insheet of less width being-Width, and a cushion of crescent shape in cross section interposedbetween said inside and outside sheets and cemented to the inside sheet,said cushion embodying a ply of chrome leather covering its outer facewith the smooth side toward the 'tread of the tire and left free andunattached to said outside sheet to form an arched deflecting surface.

In testimony whereof I aflix my signature in presence of two witnesses.
